Abstract (en)
A snap-action electric switch includes a housing (2) containing a snap-action mechanism (16) movable by a plunger (22) between a rest position and a displaced position, the snap-action mechanism (16) comprising a thin leaf spring with three parallel legs (28,30,32) the integral one ends of which constitute a contact member, at least one of said legs (28) being longitudinally stressed such that, on movement of the unstressed leg or legs (30,32) beyond an overcentre position by the plunger (22), the contact member snaps from its rest position to its displaced position. The other end of the or each unstressed leg (30,32) is mounted to be movable with the plunger (22) whereby, on guided linear movement of the plunger (22) within the housing (2), the other end of the or each unstressed leg (30,32) is moved bodily with the plunger (22) to achieve said overcentre position of said unstressed leg or legs (30,32). <IMAGE>
